UNITÉ DE REGISTRE À DÉCALAGE ET SON PROCÉDÉ D'ATTAQUE, CIRCUIT D'ATTAQUE DE GRILLE ET APPAREIL D'AFFICHAGE

摘要

A shift register unit and a driving method thereof, a gate driving circuit and a display device. In the shift register unit, an input module outputs a pull-up control signal to a pull-up module based on a first DC voltage signal and a start signal, the pull-up module outputs a shift signal via a first output port and output a start signal for a next stage of shift register unit via a second output port based on a second DC voltage signal and a clock signal, a pull-down control module outputs a pull-down control signal to a pull-down module based on the second DC voltage signal, a third DC voltage signal and the clock signal, the pull-down module outputs to the pull-up module a pull-down signal for the first output port, the second output port and a pull-up point, a reset module resets the pull-up module based on a fourth DC voltage signal and a reset signal. DC voltages are used as input signals of the pull-up module and the pull-down control module, which is stable and has a small power consumption.
